Question

This is a question about coding in python. I think that the question is asking me to code the following: Implement the scalar product of 2 vectors in 2-space, using two tuple parameters (the function scalarProduct2). Write a docstring; then write some test function calls (can I pick any data for this? - the question gave these examples data examples: (1., 1.) dot (2,3) = (1.,1.) dot (2,0) = (1., 1.) dot (0,2) = (1., 1.,) dot (4,5) = ); then implement the body of the function ( I am not sure what this means - run the function?)

Here is the formula to compute the scalar product of two vectors a and b

def scalarProduct(vectorOne, vectorTwo):
    # first check the element count in both the tuples are same
    # if they are same only then we proceed to find the scalar product
    if len(vectorOne) == len(vectorTwo):

        scalar_product = 0
        # iterate over each element of the two tuples
        for i in range(len(vectorTwo)):
            # multiply the elements at the same index
            # and add it to the scalar_product variable
            scalar_product += vectorOne[i] * vectorTwo[i]
        # return the value
        return scalar_product
    else:
        # incase the element counts are not same
        print('The dimensions of the two vectors are different. Cannot compute scalar product.')


def main():
    # create 3 tuples assuming they are vectors
    v_one = (1., 1.)
    v_two = (2., 3.)
    v_three = (4, 5)

    print('Scalar Product is: {}'.format(scalarProduct(v_one, v_two)))
    print('Scalar Product is: {}'.format(scalarProduct(v_one, v_three)))
    print('Scalar Product is: {}'.format(scalarProduct(v_three, v_two)))


main()
